Additionally, Zhong et al found that THZ1, an inhibitor of CDK7, induced apoptosis and inhibited the proliferation of liver cancer cells by reducing RNAPII-CTD phosphorylation, inducing p53 expression, and inhibiting anti-apoptotic gene expression.16Therefore, RNAPII and cell cycle-related factors may play an important unknown role in the progression of NAFLD to HCC, which needs to be confirmed. Here, CDK7 is linked to hepatocellular carcinoma.
